%description
Implements shape-based clustering algorithms for multidimensional
longitudinal data based on the Fréchet distance. It implements two main
methods: MFKmL (Multidimensional Fréchet distance-based K-means for
Longitudinal data), an extension of the K-means algorithm using the
Fréchet distance originally developed in the 'kmlShape' package, adapted
for multidimensional trajectories; and SFKmL (Sparse multidimensional
Fréchet distance-based K-medoids for Longitudinal data), a K-medoids-based
clustering algorithm that incorporates variable selection. These tools are
designed to enhance clustering performance in high-dimensional
longitudinal data settings, particularly those with time delays,
variations in trajectory speed, irregular sampling intervals, and noise.
This package implements methods derived from Kang et al. (2023)
<doi:10.1007/s11222-023-10237-z>.
